the style glabrous, ovary aborted, and a short, annular, glabrous disk 
present. Fruit obovoid, indehiscent, woody, -1 to 5 cm long, strongly 
rugose when dry, densely fulvous-hirsute or tomentose, indehiscent, 
5-celled, each cell with a thick 2.5 cm long seed. 
Mindanao, Lake Lanao, Camp Keitliley, Mrs. Clemens 7 25, September-October, 
1906, and additional material without numbers collected in January, February, 
March, April, June, and September, 1907. 
A striking genus, apparently allied to Chisocheton and Dysoxylum, but very 
distinct from both, and so far as T am able to determine, from all others in the 
family, well characterized by its very large flowers, 5-celled ovary, 20 stamens 
which are hirsute, 20-toothed staminal tube, and 5-celled indehiscent fruit. 
According to the collector, an erect, unbranched, or slightly branched tree, 4 
to 0 m high, the trunk 5 to 10 cm in diameter, the leaves crowded at the apex 
of the trunk, the inflorescence axillary, pendulous.

Chisocheton dementis Merrill sp. nov. 
Arbor maxima, glabra, inflorescent.iis exceptis; foliis alternis, usque ad 
60 cm longis, 2- ad 5-jugatis; foliolis subcoriaceis, pallidis, elliptico- 
oblongis vel oblongis, 15 ad 30 cm longis, oppositis, breviter acuminatis, 
nervis utrinque ca. 10 ; paniculis axillaribus, foliis subaequalibus, pube-

A tree reaching a height of 30 m. Branches thickened, reddish-brown, 
glabrous. Leaves 60 cm long or less, 2- to 4-jugate, the rachis produced 
and puberulent at the tip and with few undeveloped leaflets ; leaflets op- 
posite, elliptical-oblong or oblong, subcoriaceous, glabrous, pale, 15 to 30 
cm long, 7 to 10 cm wide, sometimes slightly falcate, apex short-acuminate, 
base acute or rounded, slightly inequilateral; nerves about 10 on each 
side of the midrib, prominent beneath, the reticulations lax; petiolules 
1 cm long or less. Panicles axillary, about as long as the leaves, 'the 
lower branches 15 cm long or less, puberulent, few-flowered. Calyx 
cup-shaped, rugose, densely pubescent, about 4 mm long and wide, trun- 
cate or obscurely toothed, the pedicels short and thick. Petals 5, linear- 
lanceolate, thick, about 16 mm long, 2 mm wide, glabrous inside, densely 
appressed-hirsute outside, recurved in anthesis. Staminal tube cylin- 
drical, densely hirsute, about 12 mm long, 3 mm in diameter, cleft at 
the apex into 6 oblong, truncate teeth, 3.5 mm long, 1.5 mm wide. Sta- 
mens 6, alternating with the teeth of the staminal tube; anthers 3 nun 
long. Disk none or very short. Style 12 mm long, hirsute, 5-sulcate, 
gradually narrowed upwards; stigma capitate, 1 mm in diameter.

ber, 1907. 
A species well characterized by its hirsute flowers and the curious prolonga- 
tion of the leaf-rachis, with undeveloped leaflets. Resembling Chisocheton cuming- 
ianus (C. DC.) Harms, but the flowers very different.
